Diffusion and Performance of Modular Production in the U.S. Apparel Industry

This article examines the determinants of the diffusion of team production systems (modular assembly) and the impact of these systems on firm performance relative to traditional assembly systems in the apparel industry. The article draws on an extensive survey providing detailed information on a wide range of manufacturing practices and retail relationships in the U.S. apparel industry. We find that recent diffusion of modular practices is driven primarily by the product market. We also show that modular systems affect business‐unit performance (particularly operating profits) where they are combined with complementary investments in information systems linking apparel suppliers with retail customers.
